TrialKit supports Apple iOS and Android, via native mobile apps on both Apple and Google Play Stores. The apps can be used by patients for completing their own forms.

Patients without access to any mobile devices can also use a web browser site to enter their login pin and complete any forms due. The main disadvantage of using a web browser is the patient will need to sign in every time there is a form to complete. The app, on the other hand, will remain logged in on an already-secure device.

The study builder has the option of inserting all appropriate links and login information in the patient notifications.

As a final alternative, for patients that cannot provide an email, or for situations where it does not make sense for the patient to establish their own sign in, forms can be completed in a clinical setting, via the app, by using the handoff function.
